Appearing on Good Morning America on Tuesday, Smart - a backing dancer - opened up about his relationship with the 42-year-old star.

"I don't think it was [love at first sight] for either of us," he explained. "It was just very natural how it happened. There was nothing before, no flirting, nothing."

Smart, who serves as chief choreographer on Lopez's current tour, also revealed his approach to working so closely with his girlfriend, adding: "Sometimes I tell her something, give her notes. But at the end of the day, you know, it doesn't matter what position is what, because she's the boss, you know?"
